We note that the hidden-charm pentaquark states, $P_{\\psi}^{N}(4312)$, $P_{\\psi}^{N}(4440)$, and $P_{\\psi}^{N}(4457)$, have only been observed in the $J/\\psi p$ channel. In this work, we employ the effective Lagrangian approach to systematically investigate the two-body and three-body decays of the heavy quark spin symmetry multiplet of hadronic molecules $\\bar{D}^{(*)}\\Sigma_c^{(*)}$.
